Surface-related states in oxidized silicon nanocrystals enhance carrier relaxation and inhibit auger recombination
Othonos, Andreas S.; Lioudakis, Emmanouil E.; Nassiopoulou, Androula Galiouna (2008)We have studied ultrafast carrier dynamics in oxidized silicon nanocrystals (NCs) and the role that surface-related states play in the various relaxation mechanisms over a broad range of photon excitation energy corresponding ...

Carrier relaxation dynamics in SnxNy nanowires grown by chemical vapor deposition
Othonos, Andreas S.; Zervos, Matthew (2009)Carrier relaxation dynamics in tin nitride (SnxNy) nanowires have been investigated using femtosecond transient absorption spectroscopy. The nanowires were grown directly on quartz using chemical vapor deposition and had ...
